Abstract

A lighting system for and method of commissioning LED light fixtures is disclosed. The LED light fixtures include a controller unit that is programmed with lighting firmware and an on-board light sensor that is responsive to visible light signals from a light source. In operation, the light sensor is irradiated visible light signals and/or visible light sequences that instruct the LED light fixture via the controller unit to join a group, be locked into a group, run lighting programs and/or become un-locked from a group.

First claim

What is claimed is:

1. A method of commissioning lighting devices to join a group of light fixtures within a wireless network, the method comprising:
transmitting group information over the wireless network;
receiving the group information via radio transceivers on the light fixtures;
irradiating light sensors on each of the lighting devices with a first visible light signal, thereby instructing each of the lighting devices to join the group; and
irradiating at least one of the light sensors on the lighting devices with a second visible light signal thereby closing the group, each of the lighting devices within the group cooperatively operating in response to a condition, the first visible light signal and the second visible light signal having different wavelengths and being generated from a hand-held laser.

2. The method of claim 1 , wherein the transmitting of the group information over the wireless network comprises actuating a momentary switch within the wireless network.

3. The method of claim 1 , wherein at least a portion of the lighting devices include light fixtures and wherein a maximum light output of each of the light fixtures within the group is fixed by actuating a momentary switch on one or more of the lighting devices within the group.

4. The method of claim 1 , further comprising irradiating a light sensor on a lighting device within the group with a visible light sequence from a light source, thereby instructing the lighting devices within the group to run one or more lighting programs stored in memory units on the lighting devices.

5. The method of claim 1 , wherein at least one of the light fixtures within the wireless network includes:
a light engine; and
a controller comprising:
a driver circuit for providing power to the light engine;
a controller circuit for controlling the driver circuit, the controller circuit including a micro-processor having firmware coded for instructing the light fixture and commissioning the light fixture to cooperatively operate with the lighting devices joined to the group of light fixtures within the wireless network; and
a light sensor for receiving command signals from visible light signals, the light sensor coupled to the controller circuit for initiating the firmware of the micro-processor in response to the command signals to run and commission the light fixture to cooperatively operate with the lighting devices joined to the group of light fixtures.

6. The method of claim 5 , wherein the light fixture further includes a motion sensor for controlling power to the light engine based on detected motion.

7. The method of claim 6 , wherein the light fixture further includes a manual switch for initiating firmware from the micro-processor to set a maximum light output of the light fixture.

8. The method of claim 7 , wherein the light sensor differentiates mono-chromatic light of different wavelengths.

9. The method of claim 5 , wherein the light sensor is further responsive to receiving a light sequence from a visible light source to initiate firmware on the micro-processor to run one or more lighting programs stored on a memory unit of the light fixture.

10. The light fixture of claim 5 , wherein the light sensor controls power to the light engine based on ambient light levels.

11. The method of claim 1 , wherein the lighting devices within the group include one or more motion sensors.
